UNIT 17 SPL1 Carbon Fiber Front Lip – BMW G80 M3 / G82 G83 M4
OEM++ Presence. No Drilling Required.
Where the OEM M Performance design has three small center fins flush under the bumper, the SPL1 replaces that with a single bold vector extending slightly beyond the bumper line. The corner sections are reshaped for greater depth and a wider visual stance — delivering more presence while utilizing the same OEM mounting points.
Designed for enthusiasts who want a refined yet aggressive OEM++ appearance, the SPL1 front lip enhances the front-end profile of the G8X platform without compromising fitment or ease of installation.
